Home-grown carrots can't be beaten for flavour. Pulled fresh from the soil, they fill the air with scent and provide that satisfying 'crunch' so often lacking in supermarket crops. Carrots are also rich in nutrients, containing high levels of vitamin A, beta-carotene and antioxidants.
Unfortunately, the rich scent of carrots attracts the attention of a pest called carrot root fly. Female flies lay their eggs at soil level near the shoulder of the carrot, and the larvae then eat into the roots. Early sowings are most vulnerable to attack, so delaying sowing of maincrop varieties until later in June will help protect them from root fly.
For an early crop, you'll need to take other measures to prevent carrots being filled with holes and maggots. Follow our guide to deterring carrot root fly, below.
